Making a difference? A comparison between multi-sensory and regular storytelling for persons with profound intellectual and multiple disabilities.

BACKGROUND: Multi-sensory storytelling (MSST) was developed to include persons with profound intellectual and multiple disabilities in storytelling culture. In order to increase the listeners' attention, MSST stories are individualised and use multiple sensory stimuli to support the verbal text. In order to determine the value of MSST, this study compared listeners' attention under two conditions: (1) being read MSST books and (2) being read regular stories. METHOD: A non-randomised control study was executed in which the intervention group read MSST books (n = 45) and a comparison group (n = 31) read regular books. Books were read 10 times during a 5-week period. The 1st, 5th and 10th storytelling sessions were recorded on video in both groups, and the percentage of attention directed to the book and/or stimuli and to the storyteller was scored by a trained and independent rater. Two repeated measure analyses (with the storytelling condition as a between-subject factor and the three measurements as factor) were performed to determine the difference between the groups in terms of attention directed to the book/stimuli (first analysis) and storyteller (second analysis). A further analysis established whether the level of attention changed between the reading sessions and whether there was an interaction effect between the repetition of the book and the storytelling condition. RESULTS: The attention directed to the book and/or the stimuli was significantly higher in the MSST group than in the comparison group. No significant difference between the two groups was found in the attention directed to the storyteller. For MSST stories, most attention was observed during the fifth reading session, while for regular stories, the fifth session gained least attentiveness from the listener. CONCLUSION: The persons with profound intellectual and multiple disabilities paid more attention to the book and/or stimuli in the MSST condition compared with the regular story telling group. Being more attentive towards the book and stimuli might give persons with PIMD the opportunity to apprehend the story and to be included in storytelling culture.

Bypass Rapid Assessment Triage: How Culture Change Improved One Emergency Department's Safety, Throughput and Patient Satisfaction.

PROBLEM: Emergency department waiting rooms are high risk, high liability areas for hospitals. Patients who are greeted by non-clinical personnel or who are not being placed in available beds increases wait times and prevent patients from receiving timely treatment and access to care. METHODS: A multidisciplinary team was convened to review best practice literature and develop and implement an immediate bedding process. The process included placing a greeter nurse in the waiting room who performs a quick patient assessment to determine acuity. Based on that acuity, the greeter nurse then places the patient in the appropriate available bed. RESULTS: We established our Bypass Rapid Assessment Triage process and improved door-to-triage, door-to-bed, and door-to-physician times while enhancing patient satisfaction. IMPLICATIONS FOR PRACTICE: A system should be in place that allows for immediate bedding wherever possible. Transitioning to immediate bedding requires a culture change. Staff engagement is essential to achieving such a culture shift.

Staff interactive style during multisensory storytelling with persons with profound intellectual and multiple disabilities.

BACKGROUND: Multisensory storytelling (MSST) is an individualised activity for people with profound intellectual and multiple disabilities (PIMD) in which a story is being told with an emphasis on sensory experiences and social interaction. MSST is a promising approach, but needs more empirical research evidence. In general, there is a lack of research about staff interaction during specific activities with people with PIMD. In the present study, we explored the possibility to describe staff interactive style during MSST making use of a global coding instrument. METHODS: Twenty dyads of a person with PIMD and a professional caregiver participated in an observation study. The caregivers received training in MSST and told a multisensory story to their client once a week, for a period of 10 weeks. The first, fifth and last session were recorded on video. Staff interactive style was coded using an adapted version of the Maternal Behavior Rating Scale, with a consensus rating procedure. RESULTS: Professional caregivers scored moderately on the Maternal Behavior Rating Scale. Repeated measures analyses showed no change in time. We did not find a relationship between staff interactive style and client or staff characteristics. CONCLUSIONS: The Maternal Behavior Rating Scale contributes to our understanding of staff interactive style during activities with people with PIMD. Specifically for MSST, the moderate scores on the interactive style dimensions were unexpected, because the individualised MSST activity created an optimal situation for high-quality interaction with people with PIMD. Because the interactive style did not improve through the repetition of the activity either, these results might point to a need for staff training in achieving high-quality interaction during activities like MSST.

Medical treatment of senile cataract: clinical investigation of bendazac-lysine using objective and subjective methods.

A modified Zeiss slit lamp coupled with a digital image-processing system was used to evaluate objectively changes in lens transparency over 1 year at 4-month intervals in 150 eyes of 92 patients affected by early senile cataract. A total of 59 patients were treated daily with 1.5 g bendazac-lysine, and 33 patients constituted the control group. At follow-up, visual acuity was also tested using Snellen letter charts at variable contrast to provide an additional parameter closer to traditional methods. Results indicate that the minimal angle of resolution at 10% contrast (MAR10) and the mean gray-level value of the lens image obtained by retroillumination (MLR) are sensitive to early changes in lens transparency. Using MAR10 as a parameter, the control group showed a significant, progressive worsening of the lens status over 12 months, whereas the treated group exhibited no significant changes. MRL indicated the same behaviour as MAR10, although lens damage was detected later in the control group. The results show that bendazac-lysine may delay the formation of lens opacities.

Neurophysiological and CSF immunological study of 19 patients affected by acute idiopatic optic neuritis.

We studied 19 patients affected by acute idiopatic optic neuritis (ON), with neurophysiological tests: visual (VEP), somatosensory (SSEP), acoustic (ABR) evoked potentials and study of the blink reflex (BR), and with cerebrospinal fluid (CSF) examination, in order to detect "silent" lesions in the central nervous system (CNS) and/or immunological alterations, suggestive of multiple sclerosis (MS). The percentage of cases with at least one altered CSF IgG parameter (IgG index, IgG synthesis/day and IgG oligoclonal bands) has been higher than that of cases with one or more altered neurophysiological tests, regardless of the apparently intact eye VEP. If we also included this last test, the 2 percentages become identical. The validity of these tests in predicting the evolution of ON in MS is discussed.

Incremental binocular amplitude of the pattern visual evoked potential during the first five months of life: electrophysiological evidence of the development of binocularity.

The amplitude of the pattern visual evoked potential (VEP) of a binocular stimulus has been shown to be generally larger than the VEP obtained monocularly. There is evidence that this effect can be considered an electrophysiological index of fusion. To study how binocular vision develops in infancy we evaluated the incremental binocular amplitude (IBA) in three infants in a longitudinal investigation during the first five months of life. The stimuli were phase-alternating square-wave gratings with spatial and temporal parameters chosen to be appropriate for neonates. IBA was defined as the percentage increment of the largest binocular response compared with the monocular response. In the first two months of life IBA values were near zero, that is, no summation occurred. Between the second and third month IBA values rose markedly and after the third month its value was greater than 100%, demonstrating binocular facilitation. Thus in the first two months of life the eyes do not seem to cooperate as in adults. By the second and third month the binocular pattern VEP reflects an increasing binocular interaction. Other studies of the development of stereopsis have also found evidence of binocularity at similar ages.

Evidence that 2-phenylpyrazolo[4,3-c]-quinolin-3(5H)-one antagonises pharmacological, electrophysiological and biochemical effects of diazepam in rats.

The effects of the acute administration of 2-phenylpyrazolo[4,3-c]quinolin-3(5H)-one on diazepam-induced behaviour and electrophysiological activity were studied in rat. The compound, in doses of 5-10 mg/kg (i.p.), which per se did not induce alterations in spontaneous locomotor activity, antagonised the sedative effect induced by 5-10 mg/kg (i.p.) of diazepam. The injection of diazepam in rats, induced a profound reduction in the first negative wave of the recording of the visual evoked potential used as a sensitive electrophysiological test, in vivo. 2-Phenylpyrazolo[4,3-c]quinolin-3(5H)-one (10 mg/kg, i.p.) caused a recovery of the amplitude of the first negative wave within a few minutes. This result was confirmed by the finding that 2-phenylpyrazolo[4,3-c]quinolin-3(5H)-one, injected acutely in rats, pretreated with diazepam exhibited the capacity to antagonise the binding of [3H]diazepam determined in vitro on synaptic membrane preparations from cortex. The comparison of the pattern of the visual-evoked potential, recorded after the injection of 2-phenylpyrazolo[4,3-c]quinolin-3(5H)-one (50 mg/kg) with the patterns recorded after the injection of ethyl-8-fluoro-5,6-dihydro-5-methyl-6-oxo-4H-imidazolo(1,5a) (1,4)benzodiazepine-3-carboxylate (50 mg/kg) and ethyl-beta-carboline-3-carboxylate and 1-methyl-beta-carboline demonstrated that 2-phenylpyrazolo[4,3-c]quinolin-3(5H)-one is devoid of intrinsic activity.

Supersensitivity of benzodiazepine receptors in hepatic encephalopathy due to fulminant hepatic failure in the rat: reversal by a benzodiazepine antagonist.

Benzodiazepine receptors were studied in rats with hepatic encephalopathy due to fulminant hepatic failure induced by galactosamine. [3H]-Diazepam binding studies on brain synaptic membranes of rats with mild and severe encephalopathy show a significant increase in the number of receptors in both stages of coma. [3H]Diazepam binding to synaptic membrane preparations from rats in the mild or severe stage of encephalopathy hyper-responded to the stimulatory effect of gamma-aminobutyric acid (GABA) applied in vitro at doses which for control rat preparations were in a subthreshold range. The effect of GABA was shown to be specific, since it was blocked by bicuculline methiodide. The sensitivity of benzodiazepine receptors in hepatic encephalopathy to nanomolar concentrations of GABA, which induced a significant increase in their affinity, seems to indicate a functional supersensitivity of benzodiazepine receptors in vivo in both mild and severe stages of encephalopathy. The phenomena described may be attributed to a partial degeneration of nerve terminals in hepatic encephalopathy, leading to a supersensitivity of benzodiazepine receptors, which parallels the previously described denervation supersensitivity of GABA receptors present in this animal model of fulminant hepatic failure. These findings may account for the brain hypersensitivity to sedatives administered to patients with liver diseases. The administration in vivo of a benzodiazepine antagonist, 2-phenylpyrazolo[4,3-c]-quinolin-3(5H)-one, counteracted the hypersensitivity of benzodiazepine receptors in the mild stage of encephalopathy.(ABSTRACT TRUNCATED AT 250 WORDS)

Visual evoked potential: a diagnostic tool for the assessment of hepatic encephalopathy.

Visual evoked potential recordings were examined in 45 liver cirrhosis patients with (n = 29) and without (n = 16) encephalopathy, in 15 normal volunteers, and in one patient with an opioid induced stupor state. Visual evoked potential parameters were classified on the basis of EEG recordings. Plasma concentrations of amino acids, octopamine, and ammonia were assayed in order to document the metabolic change of hepatic encephalopathy. Latencies and wave patterns recorded after flash stimulation differentiated the four degrees of the coma one from another according to EEG classification in the 29 patients with encephalopathy. In the group of 16 patients without clinical and EEG evidence of encephalopathy the visual potential recordings discriminated a group of patients (n = 10) in a preclinical stage of encephalopathy. Biochemical parameters and subsequent clinical observation of patients confirmed our judgement of a preclinical stage of encephalopathy. These results suggest that visual evoked potentials are a simple, suitable and objective method for differentiating the degrees of encephalopathy and for identifying the preclinical stage of encephalopathy.

Permanent inferior binasal quadrantanopsia in pseudotumor cerebri.

A sixty-year old patient had inferior nasal visual field defect in both eyes associated with papilledema. After pseudotumor cerebri was diagnosed and the appropriate treatment begun, the papilledema disappeared, but the visual field defect persisted. This case suggests a revision of the classical concepts concerning the pathogenesis of binasal defects from intracranial causes and emphasizes the risk of loss of vision inherent in long-standing papilledema.

Visual evoked potentials in encephalopathy induced by galactosamine, ammonia, dimethyldisulfide, and octanoic acid.

Visual evoked potentials were utilized to examine the neuronal transmission changes provoked by galactosamine-induced hepatic encephalopathy and by administration in normal animals of toxins presumably involved in the pathogenesis of hepatic encepalopathy. Separate acute administrations of ammonia, dimethyldisulfide, and octanoic acid induced lethargy, convulsions in the case of the first two, and coma with visual-evoked potential patterns that never resembled the evoked potentials recorded in hepatic coma. By contrast, single and repeated administrations of the three above-mentioned toxins together at lower doses induced lethargy and coma with visual-evoked potential patterns similar to those observed in galactosamine-induced hepatic coma. These observations, together with previously published data, are consistent with the concept that the synergistic interaction of these toxins plays a significant role in the pathogenesis of hepatic encephalopathy.

Vision in the neonate (full-term and premature): preliminary result of the application of some testing methods.

Little information is available on the functionality of the visual system in neonates. Comparison was made between neonates born at full term and prematures equated for conceptional age, using two methods of investigation: the visual evoked potential (VEP) and the "forced preferential looking" (FPL). The results obtained by the FPL method indicate a greater visual acuity in premature subjects, whereas the results obtained by the VEP method point to no significant difference in implicit time between the two groups.

Pattern reversal visually evoked potentials in general anesthesia.

Various authors have tried to determine visual acuity both electrophysiologically (Sokol, 1976 and 1978; Marg et al., 1976; Maffei and Fiorentini, 1977) and with psychophysical methods (Teller et al., 1974; Banks and Salapatek, 1976; Atkinson et al., 1976) in awake children. Our experiments try to verify the possibility of assessing visual acuity in children under Ethrane anesthesia. We conclude that under Ethrane anesthesia VEPs produced by phase-alternating square-wave gratings do not allow a fine assessment of visual acuity. Gross indications of visual acuity can however be obtained.
